【 摘 要 】

Start Optical fibers are one category of specialty fibers originally developed for light transmission (fiber optic) and information (optical cables). The fiber consists of a core surrounded by a cladding. Standard polymer optical fiber (POF) is transferring light across its axis by the mechanism of total internal reflection. In the side emitting plastic optical fibers (SEPOF) the light leaks out from their surface. The conditions for obtaining side illumination can be derived from POF geometrical model composed of two materials with different refractive indexes. The main aim of this contribution is description of SEPOF optical properties and their efficient embedding into fibrous structures for creation of line illumination hybrid structure useful for design purposes and creation of safety textile structures with active visibility in shadows. The special device for measurement of light intensity on surface and cross section at various distances from light source is described. Light intensity of textile structures is compared with light intensity of fibers.
